Hello again @enzg
It wouldn’t hurt to do both but mainly make sure that it’s whitelisted on the hosting end. You should be able to add a range of IPs in Cloudflare but if you need assistance with that I would recommend contacting their support. The 401 error is unrelated to a Wordfence block. I would also check the htaccess file for anything restricting wp-admin access. It seems like something outside of Wordfence is blocking access and your hosting provider would be a good place to start.
If after whitelisting these IPs, you’re still having issues, could you send a diagnostic report to wftest @ wordfence . com? You can find the link to do so at the top of the Wordfence Tools > Diagnostics page. Then click on “Send Report by Email”. Please add your forum username where indicated and respond here after you have sent it.
Let me know if this helps!
Thanks!
